Addition: 3 Digits Plus 2 Digits (Multiple Solutions)
Addition: 3 Digits Plus 2 Digits (Multiple Solutions)
Typical practice problems don’t move students up Bloom’s Taxonomy. With this framework, you’ll see kids stop and really think about how to approach multi-digit addition.
Gr 3-6
Subtraction: 3 Digits Minus 2 Digits (Multiple Solutions)
Subtraction: 3 Digits Minus 2 Digits (Multiple Solutions)
Typical practice problems don’t move students up Bloom’s Taxonomy. With this framework, you’ll see kids stop and really think about how to approach multi-digit subtraction.

What If There Were No Hundreds Place?
What If There Were No Hundreds Place?
Imagine a world with no hundreds place. We’d have to call it ten tens instead. But then, what would we call the thousands place? How would we read 9999? What if we added one more?
Gr 4-5
How Many Ways: 2 Digit ÷ 1 Digit = 1 Digit
How Many Ways: 2 Digit ÷ 1 Digit = 1 Digit
How many different ways can you make this math statement true using only the digits one through nine?
Gr 3-4
Math Curiosity: Four Squares
Math Curiosity: Four Squares
Every positive integer can be written as the sum of (at most) four perfect squares!
Gr 1, 2, 3, 4, 8
Place Value (Beyond Base 10)
Place Value (Beyond Base 10)
Place value is something we cover in elementary school. It seems simple, but I’d wager that very few adults really understand the topic. I sure didn’t until I worked with non-base-10 number systems in college. Your students can get a taste of this mind-boggling experience by imagining what it would be like if we didn’t have the number 9. What would each digit represent then?
